ALBERT CHARLES DAVIS, OF BOOTLE, ENG-LAND.

ICE-MAKING APPARATUS.

Specification of Letters Patent.

Patented Aug.. 3, 1915.

Application filed February 18, 1914. Serial N o. 819,408.

T0 all whom it may concern Be it known that I, ALBERT CHARLES DAVIS, a subject of the King of England, residing at 20 Morningside road, Bootle, in the county of Lancaster, (late of 166 Wadham road, Bootle, in the county of Lancaster,) England, refrigerating engineer, have invented certain new and useful Improvements in or Relating to Ice-Making Apparatus, of which the following is a specication.

This invention relates to the wall plates or partitions employed in the plate or wall system of ice making, and has for its object to provide a wall which shall be simple in construction and therefore cheaply manufactured, and whereupon the formation of ice shall be expedited.

It has heretofore been proposed to build a wall of alternate pipe lengths and horizontal series of hollow cast iron sections, the top and bottom faces of the latter being groo-ved to partially inclose the pipe lengths they interlie for the purpose of fitting. Now, a wall according to the present invention comprises a continuous freezing pipe coil, say of the type now commonly employed in the plate or wall system of ice making, and a plurality of solid metal blocks or sections, the adjacent or opposite faces whereof (and preferably the ends also) are grooved or recessed to inclose the coil and also to make contact therewith.

I will further describe my invention with the aid of the accompanying sheet of explanatory drawings, in which Figure l is a longitudinal section, and Fig. 2 a plan view, of a part of a freezing tank or chamber provided with conducting walls or partitions constructed according to my invention. Fig. 3 is a transverse section of a wall.

In said drawings, a generally represents a freezing tank, the side walls al whereof are provided with oppositely arranged vertical slots or recesses b. c are solid metal blocks or wall sections laid one on top of another so as to form a conducting wall, and the Copies of this patent may be obtained for ends whereof fit in pairs of said wall recesses or slots 5,' both meeting or butting faces of said wall sections c are provided with longitudinal grooves or recesses ai and the ends thereof are also provided with grooves or recesses e for the purpose of shrouding the bends of the coil.

f indicates a freezing pipe coil led in zig-zag manner through said recesses Z c of said wall sections and being in contact with the walls of said recesses in order that the reduction of temperature of the wall faces shall not be impeded.

In use, the spaces between the conducting walls or partitions of a freezing tank are lled with water to a suitable height, and when in action ice forms upon each side of a wall, the ice formation proceeding comparatively rapidly outwardly from the faces of the metal.

Ice, after forming to the required thickness, is released from the conducting wall by circulating hot gases or liquid through the coil thereof, and through hollow plates, boxes, or pipes, arranged immediately under and at each end of the ice block.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is In an ice making apparatus, a freezing tank having walls thereof provided with vertically disposed recesses, a sinuous pipe coil extending from one recessed wall to the other, and superimposed metal blocks having the ends thereof extending into the recesses of the tank walls and the ends and confronting faces of said blocks provided with grooves to receive the pipe coil and contact therewith, said blocks providing smooth uninterrupted vertical walls in proximity to the pipe coils.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT CHARLES DAVIS.
